Description

Selbsttätiger Rohrreiniger für Kondensatorrohre. VorliegendeErfindung betrifft einen selbsttätigen Rohrreiniger, welcher insbesondere für Kondensatorrohre Verwendung finden soll. Es ist schon bekannt geworden, in Wärmeaustauschapparaten Wirbelvorrichtungen aus Lederstreifen, Hanfkordel u. dgl., welche schlechte Wärmeleiter sind, einzubauen, die von dem durchströmenden Wasser in Bewegung gesetzt und so den Ansatz von Kesselsteinbildnern verhindern. Auch hat man versucht, das Ansetzen von Kesselstein dadurch zu verhindern, daß feste Drahtspiralen in die von Wasser durchflossenen Rohre eingebaut wurden. Ferner ist es bekannt, Ringe um wasserumspülte Rohre anzuordnen, die, durch den Wasserstrom in Drehung versetzt, die erwähnte Wirkung zeitigen. Aber diesen Einrichtungen hafteten manche Nachteile an, welche bei dem Erfindungsgegenstande beseitigt sind. Derselbe ist im wesentlichen dadurch gekennzeichnet, daß in jedes Rohr des Kondensators eine um ihre Längsachse drehbare Schraubendrahtfeder eingesetzt ist, die dauernd in dem Rohr verbleibt, mittels des durchströmenden Wassers in Umdrehungen versetzt wird und dadurch selbsttätig das Wasser quirlt und das Ansetzen von Ablagerungen des Wassers verhütet.Automatic pipe cleaner for condenser pipes. The present invention relates to an automatic pipe cleaner, which is used in particular for condenser pipes Should be used. It has already become known in heat exchange apparatus Whirling devices made of leather strips, hemp cord and the like, which are poor conductors of heat are to be built in, set in motion by the flowing water and so on prevent the build-up of scale builders. Attempts have also been made to start to prevent scale by inserting solid wire spirals into those of water flowed through pipes were installed. It is also known to use rings around water To arrange pipes that, set in rotation by the water flow, the mentioned effect early. But there were some drawbacks to these facilities, including the Subjects of the invention are eliminated. It is essentially characterized by that in each tube of the condenser a helical wire spring rotatable about its longitudinal axis is used, which remains permanently in the pipe, by means of the water flowing through is set in revolutions and thereby automatically whirls the water and the attachment prevents water deposits.

Durch diese drehende, schraubenförmige Fortbewegung der Spirale wird zunächst erreicht, daß der Rohrquerschnitt nicht verengt wird, da Schwimmer oder sonstige Einbauten fehlen. Dieses ist besonders wichtig, wo schmutziges Fluß-- und Grubenwasser verwende( wird, denn die erwähnten Einbauten verengen den Querschnitt, und zu hohe Wasser- und Dampfgeschwindigkeiten können den Betrieb gefährden. Auch werden bei dieser neuen Vorrichtung Wärmeübertragungsflächen nicht verdeckt, so daß dadurch keine Kühl- oder Heizfläche verlorengeht. Ferner kommt die Spirale mit jedem Flächenteil der Rohroberfläche radial und achsial reibend in Berührung, so daß sich bildende Ablagerungen oder Korrosionsbläschen überall entfernt und das Ansetzen derselben verhindert wird. Außerdem ist noch der Vorteil vorhanden, daß die losgerissenen Schmutzteilchen, wieder mit dem Wasserstrom gemengt, fortgeführt werden. Endlich wird auch noch die Rohroberfläche dauernd geglättet, wodurch natürlich der Wärmeübergang verbessert und ein Schutz gegen Erosionen erzielt wird.As a result of this rotating, helical movement of the spiral first achieved that the pipe cross-section is not narrowed because floats or other fixtures are missing. This is especially important where river and dirty Use mine water (will, because the mentioned fixtures narrow the cross-section, and excessive water and steam speeds can endanger operation. Even are not covered with this new device heat transfer surfaces, so that no cooling or heating surface is lost. The spiral also comes along each surface part of the pipe surface in radial and axial rubbing contact, see above that forming deposits or corrosion bubbles are removed everywhere and that Attachment of the same is prevented. There is also the advantage that the loose dirt particles, mixed again with the water flow, continued will. Finally the pipe surface is continuously smoothed, which of course means the heat transfer is improved and protection against erosion is achieved.

Die Gesamtwirkung des Reinigers ist also ein dauerndes Druckpolieren, bei dem alle Poren der Oberfläche geschlossen werden. Dieses ist von Bedeutung insofern, als die Zerstörungen der Rohre sich überwiegend über Ziehreifen einstellen, die den Ausgangspunkt von Korrosionen geben.The overall effect of the cleaner is therefore a constant pressure polishing, in which all pores of the surface are closed. This is important insofar as as the destruction of the pipes mainly occurs via draw tires, the give the starting point of corrosion.

In der beiliegenden Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt. Die Abbildung zeigt einen Längsschnitt durch ein Rohrstück mit der im Innern angeordneten Spirale.In the accompanying drawing, the subject matter of the invention is in one Embodiment shown. The illustration shows a longitudinal section through a Pipe section with the spiral arranged inside.

In dem Rohr a befindet sich eine Drahtspirale b, die um ihre Längsachse drehbar in einem an dem Rohr befestigten Lager c ruht. Die Drahtspirale setzt sich selbsttätig in Umdrehungen, sobald und solange das Wasser das Rohr durchströmt.In the tube a there is a wire spiral b, which is about its longitudinal axis rotatably rests in a bearing c attached to the tube. The wire spiral sits down automatically in revolutions as soon as and as long as the water flows through the pipe.
